Novel Handheld Robotic System for Unicondylar Knee Arthroplasty

The Learning Curve of a Novel Handheld Robotic System for Unicondylar Knee Arthroplasty1

SUMMARY STATEMENT: Integrating new technology into the OR requires buy in from all stakeholders, from the surgeon to the OR staff. This study evaluates the “learning curve” of NAVIO robotics-assisted partial knee replacement surgery, identifying the number of procedures required to achieve a steady state surgical time.

RESULTS: + Average time over first 4 cases (tracker placement to trial acceptance) of 64.9 minutes (range 27 – 102) + Time to reach steady state defined as 2 out of 3 consecutive cases within 95% confidence interval of ‘steady state surgical time’ + Average 8 procedures (range 5-11) to each steady state
